Folks from RACK911 created a listing page called http://hostingseclist.com
Its a list of recent security notices related to web hosting industry. The list is pretty fast to notify when a vulnerability arrives and most of the cases, they include a discussion linking to Webhostingtalk. It is hard to subscribe to every product developer and keep updated with their latest bug reports. While HostingSecList seems to be collecting everything in one. They are also checking each of the bug reported before posting them online. They also list community reported bugs.
HostingSecList.com is something worth subscribing out of all spammers right these days!
